That MH Optic looks pretty comparable to the Eureka! I ended up getting for my family and myself. They both use PU coating rather than sil. I didn't know PU flaked off when I got it, but if/when that happens, I figure I'll try to re-coat it. Many people have had good results sil-treating uncoated tarps at home, but who knows if I could get it to stick with PU remnants on/in the fabric?

Things to consider.
